Rembrandt and Pablo Picasso both used intaglio, a printing technique that involves applying ink to a metal plate that has an image cut into its surface.
With this method, artists apply ink to the recessed areas of the plate rather than the top surface. The plate is then pressed onto dampened paper, which enables the paper to pick up the ink from the recessed areas.
Intaglio prints often have a plate mark, which is caused by the edges of the plate pressing into the paper. In addition, the ink dries in a thick layer above the surface of the paper, giving it a textured feel.
